摘要: Liquid aftertreatment preparations for laundry having fabric-softening, acidifying and antichlorinating properties which contain, in acidic aqueous solution, hydrogen peroxide or an organic percarboxylic acid, a quaternary ammonium compounds, and hexafluorosilicic acid and/or water-soluble salts thereof, more especially the magnesium salt, as an acidifying agent. Preparations containing magnesium salts of hexafluorosilicic acid are distinguished by particularly high stability of the per compounds.
